冠狀動脈繞道手術病人手術風險與心肺適能之相關性研究

Abstract

Introduction and objectives: The European System for Cardiac Operative Risk Evaluation II (euroSCORE II) is a validated model for predicting perioperative mortality after cardiac surgery. The role of cardio-respiratory fitness (CRF), expressed as peak metabolic equivalents (METs), as a predictor of long-term survival in patients who have previously undergone coronary artery bypass grafting (CABG) is well established. However, the correlation between perioperative risk and CRF has not been evaluated. The aim of this study was to investigate the relationship between perioperative risk and CRF in patients after CABG. Methods: Patients who underwent CABG from January 2012 through December 2013 at VGH-TPE were queried, and those who completed cardiopulmonary exercise testing (CPET) around four weeks after discharge from the hospital were enrolled. Electronic medical records were reviewarticleed to calculate euroSCORE II. Peak METs established by treadmill was used to measure CRF. Results: Twenty-nine patients (25 males+4 females) were included. The mean peak MET was 4.92±1.34, and the mean perioperative risk of mortality measured by euroSCORE II was 1.52±0.96%. An inverse correlation between peak MET and perioperative risk was identified (Spearman's correlation p=-0.508, p=0.005) Conclusions: The present study provides information not previously found in the literature that euroSCORE II is correlated with CRF in patients after CABG. For those with a higher euroSCORE II, aggressive phase I and phase II cardiac rehabilitation are indicated. Further studies to justify the use of euroSCORE II as an indicator of CRF in other disease categories are warranted.
